Managing personal Outlook.com account settings, security, and privacy
Hi SCOTTMANSFIELD1
Thanks for reaching out! My name is Dane and i'm an Independent Advisor and a Microsoft user like you.
Creating an Email alias will not achieve what your desired setting, email Alias will only give you another email account name but it will share the same mailbox as the original account. Your second option is actually the best option, you can create a second microsoft account by using the sign up link, you can use the same information on the first account it is not an issue.
